Hi, The raw generator is quite complete. As far as I can see it does work, and has the option for a compatibility layer for the old core and produces the correct code (although that's hard to verify with 300+ modules ;) ). In addition I don't see many points of improvement to the output nor the internal structure. Therefore I would like to know if the generated code and program is correct/good/according to specification i.e. should it be changed? Because (as said) as far as I can see it is all working. For those of you who like to build it, the instructions are at the end. If people would prefer an archive above the hassle of generating it themselves please let me know. Lars * Build instructions * The non hackage dependencies are: opengl-api [1] includes some modifications on noteeds (thank you) package for parsing the spec files. CodeGenerating [2] a package with utility functions on top of haskell-src-exts The generator can be found at [3] when compiled run it from the directory with the source files (build root). When running the generator the following options are probably useful: --no-vendorf=novendor (removes the extensions from vendors listed in the novendor file, to reduce the output a bit) -o output (output to the `output` subdirectory) -c (generate compatibility with the current OpenGLRaw) [1] https://github.com/Laar/opengl-api [2] https://github.com/Laar/CodeGenerating [3] https://github.com/Laar/OpenGLRawgen
